2019 Tri- state forestry conference has been postponed until 2020. Jay Hayek from Illinois will be heading up future tri-state conferences. Dr. Randall is now with Michigan State University and will assist at future events - see you all March 14th 2020.

Jesse Randall has taken a position at Michigan State University in the Dept of Forestry. ISU is in the process of hiring a new Extension forester but that can take up to a year and a half to get the right candidate. ISU has put into place a system so your forestry needs will be met, but we ask for your understanding during this time. Dr. Randall can be reached at 906 786 1575 if you need assistance.

Treatment for Emerald Ash Borer

1.The MostEffective treatment window for EAB Adults and 1st instar larvae is April, May, first 2 weeks of June 2018.

DO NOT WASTE YOUR MONEY ON TREATMENTS in mid to late summer . Commerical treatements take 1-4 weeks to be effective and DIY treatments take 4-8 weeks so they will miss the peak adult emergence completely if administered after May 2018. For More treatment info see ISU's Publication PM2084

2. There are NO treatments on the market which are a one and done cure-all! You will need to treat every 1-3 years depending on product used. Injection treatments will do damage to the vascular structures in the tree so don't start before the infestation arrives in your town!

3. Be carefull of the random "knock on the door" and the pressure sales tactics. Reputable companies will not do this and in most cases, if you call a local company, they will try to dissuade you
from treating your trees until EAB is found within 15 miles of your home!

4. Call your local extension office if you have any questions before you agree to any treatment (you can find the number by clicking on your county in the map at the bottom of this page.)
